magazine, and these ejecting' devices are controlled by individual clutches corresponding to each magazine. The condition of these clutches, that is, whether they are actively or inactively related is controlled by the cost keys and by the payment keys or pay keys. These. clutches are arranged in a gang on the same shaft and the operation of this shaft is itself controlled by a main clutch which must be closed before the shaft can be rotated to eject the coins required. The gang clutches which control the ejecting devices of the first division are normally closed and when any cost key is depressed it throws open the gang clutches of the first division corresponding to its number. 'For instancerwhen the 30ey cost key is depressed it opens the 25e clutch and 5e clutch of the first division inhibiting their ejecting mechanisms. so that it leaves the ejecting mechanism of the first divisiof` operating or set to eject a 50c and two 10e pieces; which gives the correctl change. The cost keys are arranged in twosets, dime keys and cent keys. The depression of om` of the cent keys normally throws out or opens one of the 10c` gang clutches of the first division and may also at the same time throw in the 5c or arri7 ofthe four 1c magazines of the second division.

Under certain conditions. however. a special mode of operation is necessary which supersedes the normal operation of the machine; for instance. where the cost key has been depressed it leaves thc 25e ejecting mechanism and the 5e ejecting mechanism of the first division intact so that 30e will be eiected. However. if one of the cent keys is depressed following thc depression of wthc Tflc key. the normal operation usually affected hy this cent key cannot take place' for there is no 10g. rang clutch then closed,y for the cent key to th row open. Under these circumstances a special operation takes place which consists in automatically throw@ in r in again the, two 10e clutches. rl"his operation itself is equivalent to throwing out a 10c clutch and therefore produces thc correct change.

Tn other cases in making change. occasion often necessitates the throwing in or throwing ont of a 5c piece and therefore the 5c ejer-ting mechanism of the first division is controlled to a certain extent hy a special clutch.

Another special operation is effected by the depression of a 25g* or 75e pay key following the depression of a 20c or 70e cost key.

Referring more particularly to thc parts of the machine. 1 represents the case on the cover Q of which at a suitable point there is arranged a plurality of magazines. i. 3. 6. 7. 8. i0. 11 and 12. These magazines are for coins of different denomination and thc magazines m-T constitute the firstV division and respectively receive coins of the dcnominalion ol' 50c. 2.3i'. 10c. 10c and 5c. 1 provide means normally set for ejecting a coin from all of these magazinesl simul- 70 taneously. The magazines 8-11 constitute the second division; the magaznn` n is for 5e pieces, and the other four magazines 9--12 contain pennies. These magazines are of simple tubular form, as indicated. An individual ejecting device is providcd corresponding to each magazine. As shown in Fig. 3, the coin rests on a sla-.lf 13 and behind the bottom coin of cach magazine a transversely guided eiecting slide 14 is pro- 80 vided. and these ejccting slides are adapted to be actuated b v horizontal push rods 15 which extend toward the rear wall of the machine and are attached rcspectivcly tc verticallyv extending armsl It. carried looselyY 85 on a longitudinally extending rock shaft 17 which extends suhstantiallv throughout the entire length of the machine as indicated. These arms 1G have hubs 1S which constitute clutch members coiipcrat ing with collars 19, which are non-rotatable on the shaft 17; and these collars arc all arranged so that they may bc slid on the shaft by means of horizontal ejector arms indicated collectivelv by the numeral 20. which extend from front to rcar of thc ma chine. all of thc said arms being pivotally supported at their forward ends on a horizontal frame-har 21. As thc collars 19 arc non-rotatable on the rock shaft 17. when the)r are in engagement with the hubs 18 of the arms they form clutches 2Q so that when the rock shaft is rocked the push rods 15 will be actuated b vjhc arms. Tn this way the ejeeting lslides 14 are actuated and 105 it will he seen that only those cjecting slides will be actuated whose clutches 2Q are closed. These clutches 22 are arranged in a `rang as indicated in Figs. l and Q alongr the rock shaft. 11o

A t the, left cnd of thc machine. as shown in Fig. 1. the main clutch 23 is provided. comprising a slidingr collar Q4. and the hub Q5. said hub being formed on an arln 26 for actuating the rock shaft. The clutch member or collar' 24 is non-rotatable on thc shaft but the hub 25 is loose. The collar 9.4 is adapted to bc slipped in and ont of engagement with the clutch member Q5 by an arm 27. said arm`bcing similar to thc arm 20. and pivotalljiy attached in thc same manner to the aforesaid franlc bar 21.

The cjccting;r slides 1l arcfnormallyY all hcld in a withdrawn position hy means of individual springs 2R which are attached to l'-'v thc arms li and hold thc said arms against a stop bal' 29 which cxtcnds longitudinally in thc machine.

and formed with an arm or dog 11a which extends upwardly so that its end lies near the left ed e of the shifting arm 2.0, as xndicated in tigs. 2 and 3. At the other end of the clutch shaft 10T, the 5in clutch coinprises a clutch member 11G which forms the huh oi an upwardly extending do 117 and this dog lies ncar the right hand et ge, of the shiftingarln 20c. Between the clutch incinbers 115 and 11G, slides a double clutch collar 11S which is non-rotatable on shat't 10T: and when this clutch collar engages the clutch member 111, the dog 115 will be rocked toward the. right if the rock shaft 107 is rocked toward the left. This reversed movement is imparted to the dogr 115 hy reason of the gears 112 and 113. When the collar 11S is in engagement with the clutch member 116 the, motion ot the clutch shaft 10T will bc in'iparted directly to the dog 117 and will rock this finger toward the left and throw the gang clutch in. The clutch shaft. 1.0i' is actuated by an arm 11h which is rigid with it and extends downwardly so as to be attached to an oli'set link 120 which extends to the. left of the niachine and passes through a slot 121 in the partition wall 45 as indicated in Fig. 2. Near this point, this link is attached pivotally to a rocker arm 122 which extends upwardly from a rock shaft 12?, mounted in brackets 124 attached to the wall rl`his rock shaft is provided with rigid arms 125 connected' by a bar 126 which |ie I under the stems 39 of the right. hand row of pay keys, that is, it lies under all of the pay keys of a denomination terminating in .3. excepting the 5 and 15e keys. A spring 12T attached under the arm 122 returns the said arxn 122 to its norliial position and returns the dcpressiblc bar 126 when it has been depressed y the stems of the keys.

ln order to return the -tnger 117 after it has been actuated the huh 116 is provided with a downwardly extendiiui,r arm 128 to which a spring 129 is attached as indicated in Fig. 8 and one end of this spring is at4 tached to a lixcd bracket or p`ost 130 extend? ing out horizontally from the aforesaid bracket 76.

ln order to shift the clutch collar 118 so as to close the 5-in clutch, or the :'i-out clutch` there is provided a clutch shifting lever 131 indicated in dotted lines in Fig. 8, pivoted on a post 131. It. should be understood that these clutches, namely the 5-in clutch and the 5-out. clutch are, controlled from the cost; keys but the mechanism which is operated throughthese clutches when closed is actuated by the pay keys. As indicated by the arrow 132 in Fig. 8 all of the dirne ke s of the cost keys when operated, throw in t e 5in clutch. If the number of the cent key following the depression of one of the dime keys of the cost keys is greater than 4, the

from the 25e key to the. 95d key.

5in clutch remains in, that is, itl remains in the position in which it is set automatically by the dime key which has just been depressed; if on the contrary the cent key which follows is less than 5 the 5in clutch 70 is opened automatically' andthe 5-out clutch is closed. ln this way sometimes the cent key may undo the work performed by the dime key. This mode oi' operation is necessary because when the number of the cent key fol- 75 lowing r is as great as 5 the 5 will not he wanted and must. be thrown out.

The mechanism for controlling' this 5e clutch lever 131 will now be described refer`- ring particularly to Figs. 2. 4, 5 and 8. 8e Between the partition wall 16 and the end `wall ot the machine a guide bracket 183 is provided in which there is mounted to slidel horizontally, a bifurcated shifting arm 131, which consists of two vertically disposed bars 13?: and 131' connected at their rear end by an integral cross bar 137. The bar 135 is provided with a plurality of notches 138 presenting inclined edges 139 which are adapted to be struck by the lower edges of 9o the plates or blades 49 which arc attached to the stems 5|) o1' thc dirne cost` keys. so that when these keys are depressed they will shift the bar toward the rear of the machine. 'lhc end ot' this bar 1?-1 is pivotally attached 96 at a cross web 14() to the aforesaid 5c clutch lever fil` which passes through a slot 1-11 in wall 413 as indicated in Fig'. i. for this purpose. ln this connection it should be understood that the order in which the cost. keys is depressed is important and the dime key should always be depressed first. TheY bar 13G -is provided with notches 142 which are similar to the notches` 13S but are in a reversed position so that they present` inclined edges 143 which may be struck by the lower edges oi the plates or blades 49 ot the cent keys le to 4e. which will ha :c the effect of throwing` the lever 141 back. and throwing the .fi-out clutch into operation in stead of the 5in clutch. These notches 142 occur however only under the. centy keys of denominations of le to 1c as indicated by the arrow 144 in Fig. 8. and as shown in Fin'. .3. From this arrangement it will he seen that any ot' the dime keys of the cost keys upon being' depressed will throw the 5in clutch into active condition and if the cent key depressed thereafter exceeds t in denomination the 5in clutch will remain closed. Il. however` the cent key depressed subsequently is less than 5c in denomination the 5in clutch will be thrown open and the -out clutch closed.

its indicated in Fig'. S the bar 126 does not extend under all of the keys in the right hand row of the pay keys but only extends Furthermore the 25e key and the 75e key will not operate the bar 126 to actuate the. link 120.

Where the operation of the machine is normal, that is, where the coins which are roduced to make change are controlled entirely by the notch bars 3.3 etc., the coins are represented by plain circles, but where any coin is produced through the operation of a spccial clutch this is indicated by cross lines upon the disk or circle representing the coin.

As indicated in each chart or table the normal condition of the machine is such that the magazines of the first division are prepared to produce exactly one dollar and this is indicated in many ot' the charts in the upper row just nndcr thc ninnhcrs imlicat ing the denomination of the different maga-- zines.

`Before proceeding to a description of the actual change making operation attention is called to the actual combinations which are met with in the practical use of the machine, and vihich must be negotiated by the ma chine. These combinations are indicated in the following table, in the left, column of which is indicated the amount paid, or ap;- gregate of the coins which are handed to the cashier in payment and this colmnn is designated Pay, in the right hand col umn is indicated the cost, of the articles which may be paid for by the amount handed to the cashier.y and this column con tains two numbers indicating the range or ca pacity thc machine must havc corrcspomling to the opposite pay key. that is, the pay key in the same horizontal row. This eolnmn is designated Cost. ln the first line of the column below, it is indicated that in making change for $1 any amount from 1c to 99 must be returned to the customer. In making change for a 95e payment the cost, of the article paid for may range in price trom 86 to94e and so on.

ln making change from a paynicnt oil Qc as indicatcrl in Fig. ll. change must bc made for articles that cost from 30d' to .ll. Thon thc 80g' cost key is depressed. as indicated at U15, thc notch har 36 corresponding to this key throws opcn all the clutchcs QQ oi' thc first division of magazines cxccpty the clutches of thc two tens which giics thcY proper change for an 80e 'purchase from one dollar. Thon thc fic kcy is depressed as indicatcd at lGfi. one oi the dime clutches is thrown open and thc four penny clutchcs arc thrown in or closed which gives 14e. which is tlul correct change from one dollar. The depression of a 95e pay key has the e'ect of reducing the change by 5, and just at this point. one observes the utility of the 5-in clutch 11G and the ii-outclntch 109 illustrated in Fig. 8. As described above. and as illustrated in Figs. 4 and 5 the 6e cost key docs not shift the bar 134 and therefore leaves the 5-in clutch closed. (which has just been closed by the 80e cost key). Depressing the 95 pay key through the medium of its notch bar 35 throws open the dime clutch which would produce, a. dime as indicated at 167, and at the same time the stem of the 95 pay key actuates the link 120 and the shaft 107 so as to actuate the :Ti-in clutch 110; hence the depression of this 9.5. key throws out 10 and throws in 5c, as indicated at 168 in Fig. 11. A similar operation takes place in making change for an article costing 89e but in this table the operation is condensed into a single line.

In making change when 95 cents is paid for a 90ey article the depression of the 90e cost key (indicated at 169) throws open all the clutches except the right hand dime clutch. As soon as the 95e key is depressed however, this dime clutch will be thrown open by the notch bar corresponding to this key and the 5-in clutch will be actuated so as to produce a 5e coin from the magazine as indicated at 170 in the table. When an article costs 91e and the payment is 95e the depression of the 90 cost key leaves one dime to come from the first division as indicated out the clutch of at 171. The depression of the 1e key throws out this dime through the operation of dofr 71 (see Fig. 2) and throws in all the clutches of the second division so that 9c is left to come from the machine. The depression of the cent key will have the effect` of throwing the 5-out clutch 109into its closed position. The subsequent depression of the 95 pay key would therefore have the effect of throwing thenickel magazine of the first division but this magazine has already been thrown out of activity by the depres sion of the 90 cost key. Therefore through the operation of its notch bar the 95 pay key simply throws open the gang clutch 22 of the nickel magazine of the second division. The operation 0f making change from a 91el article up to a 9495 article is similar to that just described but in thei table the operation has been `condensed in o single lines.

Making change from a 9 t payment is illustrated in Fig. 12 and i very simple. the range of the cost of the article being only from 81e to 8.9. The. operation is graphically analyzed near theihottom'of the table, Where it is indicated that .the depression of the 80g/f cost kcy leaves the two dime clutches of the first division closed as indicated at 172 and the depression of the 9 key simply throws open one of these dime clutches and throws in one of the 1c clutches. The operation of any of the other unit keys is Similar to the ope-ration of the 99* key. When the 90 'pay key issubsequently depressed, its notch bar 35 simply opens the remaining dime ciutch. leaving one cent change to be produced by the machine.'

In making change from 85e for articles '85e pay costing tt to 84e the operation is illustrated in Fig. 13. A depression of the cost key throws open the clutches of the 50c .magazine, and the two dime magazines of the first divisiorhand leaves the 25e, and 5c clutches closed. In connection with the 70e key, it should bc remembered that this is a special key and its depression operates to shift the bar 101 shown in Fig. 6 to open the ciutch 82a and ciose the clutch 83. This clutch 83 operates the dogs 94 and 95 and also the dogs 97 and 98 as indicated in Fig. 2. Therefore when the 6c cost key is depressed it actuates the link 86. and the dogs 94 and 95 throw open the 25e clutch and the 5c clutch, while .the dogs 97 and 98 close the two dime clutches as indicated at 173 in Fig. 13. At the same time the notch bar 36 corresponding to the 6c cost key closes all the 1c clutches so that the machine is ready to produce 2l-c change. This is the correct change from $1. The depression of the 85e pay key will now reduce this amount by 15e. This operation takes place as follows: Notch bar 35 of the 8.5 pay key directly engages the arms 20d and 20* and shifts the corresponding gang clutches 22 to their open position. This takes out 20c.

n VThe machine also substitutes 5 for the 20 removed, as follows: It should also be understood that the depression of the 6c cost key will leave the 5-in clutch 110 closed, that is, in the position in which it has been put by the depression of the 70 cost key. Therefore the 5-in clutch will operate by the depression of the 85e pay key to throw in the gang clutch of the nickel magazine of the first division. as indicated at 174. This leaves 9c to come from the machine, which is the correct change. The operation from 76a*y up to 79e is similar to this, the notch bar of the depressed cent row key simply operating to vary the number of pennies produced by the machine to give the correct change.

Inmaking change from an 85e payment for an article costing 80 the depression of the Sc key leaves two dimes to come from the first division and the depression of the key simply throws open these two dime clutches and throws in the 5c magazinev ciuteh through the operation of the 5-in clutch 110, the. said fin clutch having been closed automatically,r by the depression of the 80e cost key.

The operation of making change from 859% for an article costing from 81 to 849 is very simple, and is normal. that is,4 no special clutches are called into play. The depression of the 80;* cost key simply leaves the two dirne clutches closed. The depression of the cent key opens one of the dime clutches and closes the nickel clutch of the second division and all the one centclutches. The depression of the 85e pay key simply
